<heading id="h0001">FIELD OF THE INVENTION</heading>
<p id="p0002" num="0002">Systems and devices consistent with the present disclosure generally relate to a steering wheel connector. More particularly, systems and devices consistent with the disclosure relate to a steering wheel connector for use in automotive simulators that provides a combined mechanical and electrical connection between a removable steering wheel and the automotive simulator.</p>
<heading id="h0002">BACKGROUND</heading>
<p id="p0003" num="0003">Automotive simulation systems that simulate the experience of driving a car are used for both video gaming purposes as well as for training purposes for persons involved in driving, such as racing car drivers. To effectively achieve these video gaming and training purposes, the simulation provided by these automotive simulation systems must be able to replicate the experience of a real car with a high degree of accuracy and authenticity. However, designing an automotive simulation system that achieves a high degree of accuracy and authenticity is difficult and expensive to produce.</p>
<p id="p0004" num="0004">In order to make the simulation as realistic as possible (i.e., with a high degree of accuracy and authenticity), it is important that, in addition to the visual experience, user interface equipment, such as steering wheels and brake systems, is equal to that which is experienced in a real car. This allows for maximum learning potential in automotive simulation systems used for training, and maximum entertainment emersion potential in automotive simulation systems used for video gaming purposes. Regarding the steering wheel in automotive simulation systems, it is important that the mechanical elements, such as various buttons and controls on the steering wheel, correspond to those of a real car.<!-- EPO <DP n="2"> --> Thus, it is important to be able to exchange steering wheels in an automotive simulator such that they match the steering wheels of the real car. Further, some cars, especially sport cars, may require the steering wheel to be temporarily removed in order for the driver to easily enter or exit the automotive simulator.</p>
<p id="p0005" num="0005">In conventional automotive simulators that allow for removal of the steering wheel, typically a mechanical connector is used to connect the steering wheel to the steering axle, and a separate, electrical connector is used to create an electrical connection between the controls on the steering wheel and the automotive simulator. This makes installation and removal of the steering wheel cumbersome as it involves disconnecting the electrical cords and the steering wheel as separate operations. Furthermore, the aesthetic appearance with electrical cords dangling on the side of the steering wheel is also less than ideal, and also creates a risk of the driver of the automotive simulator getting entangled in the electrical cords, which may adversely affect the driver's experience in the automotive simulator. In view of the foregoing, it is desirable to create a steering wheel connection that avoids or at least reduces these and other associated problems.</p>
<heading id="h0003">SUMMARY</heading>
<p id="p0006" num="0006">According to a first aspect of the present disclosure, a steering wheel adapter system for an automotive simulator is provided. The steering wheel adapter system includes a first adapter formed in a distal end of the steering wheel. The first adapter element comprises at least one of a first electrical contact surface and a first optical contact surface. The steering wheel adapter system further includes a second adapter element formed in a distal end of a steering axle of the automotive simulator. The second adapter element comprises at least one of a second electrical contact surface and a second optical contact surface. The first adapter element and the second adapter element are configured to slide against each other along a plane that is substantially perpendicular to the steering axle, until a seated position has been reached, wherein the steering wheel comprises a central axis that is aligned with a central axis of the steering axle. At least one of the first and second electrical contact surfaces and the first and second optical contact surfaces make contact with each<!-- EPO <DP n="3"> --> other to establish an electrical connection, an optical connection, or both between the steering wheel and the steering axle of the automotive simulator.</p>
<p id="p0007" num="0007">In some embodiments, a steering wheel for an automotive simulator includes a distal end having a first adapter element comprising a first electrical contact surface. The first adapter element is configured to slide against a second adapter element formed in a distal end of a steering axle of the automotive simulator and comprising a second electrical contact surface. The first and second adapter elements are positioned to slide along a plane that is substantially perpendicular to the steering axle until a seated position has been reached in which a central axis of the steering wheel is aligned with a central axis of the steering axle, and the first and second electrical contact surfaces make contact with each other to establish an electrical connection between the steering wheel and the steering axle of the automotive simulator.</p>
<p id="p0008" num="0008">In some embodiments, a steering axle for an automotive simulator includes a distal end having a second adapter element comprising a second electrical contact surface. The second adapter element is configured to slide against a first adapter element formed in a distal end of a steering wheel and comprising a first electrical contact surface. The first and second adapter elements are positioned to slide sliding occurs along a plane that is substantially perpendicular to the steering axle until a seated position has been reached in which a central axis of the steering wheel is aligned with a central axis of the steering axle, and the first and second electrical contact surfaces make contact with each other to establish an electrical connection between the steering wheel and the steering axle of the automotive simulator.</p>
<p id="p0009" num="0009">By placing electrical contact surfaces in the respective adapter parts, it is possible to achieve both a mechanical and electrical contact between the steering wheel and the steering axle of the automotive simulator in a single action, rather than first having to create a mechanical connection and then separately connecting an electrical cord, as is done in current solutions. Further, the sliding operation by which the two adapter elements connect to eventually make contact with each other in a seated position, in which the electrical connection is established, also makes the installation and removal of the steering wheel a very intuitive and simple operation for a user of the automotive simulator, which can be<!-- EPO <DP n="4"> --> easily accomplished as the user enters or leaves the seat of the automotive simulator. A clean appearance is also created, in which no loose cords are sitting next to the steering wheel and steering axle, which also reduces the risk of the driver getting entangled in such cords, either while driving or while entering/exiting the automotive simulator. Further, in many cases, the space around the driver of the automotive simulator is limited. Therefore, it is a much easier operation for the driver to connect/disconnect the steering wheel to the steering axle by sliding the steering wheel in a direction that is essentially perpendicular to the steering axle, compared to a motion where the steering wheel is slid along the steering axle (e.g., pulled towards or pushed away from the driver).</p>
<p id="p0010" num="0010">In one embodiment, the first adapter element is formed as a recess and the second adapter element is formed as a protrusion. In another embodiment, the first adapter element is formed as a protrusion and the second adapter element is formed as a recess. The geometric shape of these protrusions and recesses may vary in different embodiments, but as a general rule, they are configured to match one another such that one can be slid into the other and end up in a distinct, seated position, where it is evident to the user that the steering wheel is firmly seated on the steering axle and that electrical contact between the steering wheel and steering axle has been established. By having the recess/protrusion in combination with a combination with the sliding movement to connect the two adapter elements, it is also possible to reduce the risk of the steering wheel detaching from the steering axle if a driver were to pull the steering wheel towards himself. Thus, a more secure connection is created compared to if the steering wheel were installed by simply pushing it onto the end of the steering axle.</p>
<p id="p0011" num="0011">In one embodiment, gravity acts as a contributing force in the seated position to push the first and second adapter elements together and retain them in the seated position. That is, the steering wheel is attached to the steering axle in a downward sliding motion, and the electrical contact surfaces are placed along the bottom of the adapter elements (i.e., the portion of the adapter element that is located closest to the ground). Thereby the weight of the steering wheel contributes not only to keeping the wheel in the seated position, but also to actively pushing the two electrical contact surfaces against each other to maintain electrical contact between the steering wheel and the steering axle. In some embodiments, which will be described in further detail below, a locking pin can also be inserted into<!-- EPO <DP n="5"> --> aligned holes that run through the first and second adapter elements to prevent the first and second adapter elements from separating from one another after the steering wheel has been attached to the steering axle.</p>
<p id="p0012" num="0012">In one embodiment, the first electrical contact surface is connected to one or more user controls on the steering wheel, and the second electrical contact surface is connected to the automotive simulator through wiring running inside the steering axle to a computer that hosts the software needed for operating the automotive simulator. This makes it possible to transfer user control commands from the steering wheel to the automotive simulator through the steering axle.</p>
<p id="p0013" num="0013">In one embodiment, the first electrical contact includes one or more plain metal surfaces, and the second electrical contact includes one or more spring-loaded pogo pin connectors. These types of contacts are well known in the art, thus making it possible to use the steering wheel adapter system with conventional electronics setups, which facilitates compatibility with existing automotive simulators. Having spring-loaded pogo pin connectors also allows some degree of flexibility and ensures that electrical contact is made even in a situation where the user makes a minor mistake when mounting the steering wheel onto the steering axle. Of course, there can also be other embodiments in which the first contact includes spring-loaded pogo pin connectors, and the second contact includes one or more plain metal surfaces.</p>
<p id="p0014" num="0014">In one embodiment, the dimensions of the first electrical contact surfaces are bigger than the dimensions of the contact surfaces of the pogo pins to ensure contact and depend on the spacing of the pogo pins on the second electrical contact surface. The area of the contact surface of each pogo pin could, in one embodiment, be 0.5 x 0.5 mm<sup>2</sup>.</p>
<p id="p0015" num="0015">According to a second aspect, the disclosure pertains to a steering wheel for an automotive simulator. The steering wheel has a distal end with a first adapter element comprising a first electrical contact surface, wherein the first adapter element is configured to slide against a second adapter element formed in a distal end of a steering axle of the automotive simulator and comprising a second electrical contact surface, wherein the sliding occurs along a plane that is substantially perpendicular to the steering axle until a seated position has been reached in which a central axis of the steering wheel is aligned<!-- EPO <DP n="6"> --> with a central axis of the steering axle, and the first and second electrical contact surfaces make contact with each other to establish an electrical connection between the steering wheel and the steering axle of the automotive simulator.</p>
<p id="p0016" num="0016">According to a third aspect, the disclosure pertains to a steering axle for an automotive simulator. The steering axle has a distal end with a second adapter element comprising a second electrical contact surface, wherein the second adapter element is configured to slide against a first adapter element formed in a distal end of a steering wheel and comprising a first electrical contact surface, wherein the sliding occurs along a plane that is substantially perpendicular to the steering axle until a seated position has been reached in which a central axis of the steering wheel is aligned with a central axis of the steering axle, and the first and second electrical contact surfaces make contact with each other to establish an electrical connection between the steering wheel and the steering axle of the automotive simulator.</p>
<p id="p0017" num="0017">The second and third aspects of the disclosure may be varied similar to what has been described above for the first aspect, and consequently comprises a similar set of advantages.</p>
<p id="p0018" num="0018">The details of one or more embodiments of the disclosure are set forth in the accompanying drawings and the description below. Other features and advantages of the invention will be apparent from the description and drawings, and from the claims.</p>

<heading id="h0005">DETAILED DESCRIPTION</heading>
<p id="p0021" num="0021">The following detailed description refers to the accompanying drawings. Wherever possible, the same reference numbers are used in the drawings and in the following description to refer to the same or similar parts. While several exemplary embodiments and features of the disclosure are described herein, modifications, adaptations, and other implementations are possible without departing from the spirit and scope of the disclosure. For example, substitutions, additions, or modifications may be made to the components illustrated in the drawings, and the exemplary methods described herein may be modified<!-- EPO <DP n="8"> --> by substituting, reordering, or adding steps to the disclosed methods. Accordingly, the following detailed description does not limit the disclosure. Instead, the proper scope of the disclosure is defined by the appended claims.</p>
<p id="p0022" num="0022">Systems and devices consistent with the present disclosure generally relate to a steering wheel connector for use in an automotive simulator, which allows a mechanical and an electrical connection to be accomplished between the steering wheel and the automotive simulator in a single operation and without the use of separate cords.</p>
<p id="p0023" num="0023"><figref idref="f0001">FIG. 1</figref> is a perspective view illustrating an embodiment of a steering wheel 100 for use in an automotive simulation system, such as a racing video game simulator or a professional racecar driver training simulator. As can be seen in <figref idref="f0001">FIG. 1</figref>, the steering wheel 100 has a steering handle 102, which faces the user when the steering wheel 100 is installed in the automotive simulation system. The steering handle 102 is where the user places their hands and has a number of controls for the operation of the automotive simulation system. The steering handle 102 of the steering wheel 100 is connected to a distal end 104. The distal end 104 of the steering wheel 100 connects to a steering axle in the automotive simulator, using the steering wheel adapter system, which will be described in further detail below, to secure the steering wheel 100 onto the steering axle. In order to perform that function, the distal end 104 of the steering wheel 100 comprises a first adapter element, which will now be described in further detail with respect to <figref idref="f0001">FIGs. 2</figref> and <figref idref="f0002">3</figref>.</p>
<p id="p0024" num="0024"><figref idref="f0001">FIG. 2</figref> is a rear perspective view illustrating the steering wheel 100. As can be seen in <figref idref="f0001">FIG. 2</figref>, the distal end 104 comprises a recess 106 and a first electrical contact surface 108, which together form the first adapter element. The recess 106 and first electrical contact surface 108 are configured to pair up with a corresponding protrusion and a second electrical contact surface on the distal end of the steering axle, as will be described in further detail below. In the embodiment shown in <figref idref="f0001">FIG. 2</figref>, the recess 106 has a "trapezoid" shape, which allows the steering wheel 100 to distinctly slide on to the corresponding protrusion in the steering axle and come to a distinct stop when the steering wheel 100 is fully aligned with the steering axle in a seated position. In that seated position, the first electrical contact surface 108 also touches a corresponding second electrical contact surface in the second adapter part on the steering axle, thereby enabling electrical contact<!-- EPO <DP n="9"> --> between the steering wheel 100 and the automotive simulator. One advantage with the trapezoid shape is that initially when the steering wheel 100 is being slid onto the steering axle, the width of the opening in the recess 106 is much bigger than the width of the corresponding protrusion in the steering axle, which makes it easy for the user to initially fit the two parts together. Then, as the steering wheel 106 is slid downwards, the trapezoid shape ensures that the first and second adapter elements are aligned, and that the electric contact surfaces on each element meet in a precise position, ensuring that the electrical contacts on the steering wheel 106 and the steering axle, respectively, are paired as intended. However, it should be noted that the trapezoid shape of the recess 106 is only one of many possible shapes that can ensure a distinct seated position for the steering wheel 100, and that many other shapes that achieve the same purpose can be envisioned by those having ordinary skill in the art.</p>
<p id="p0025" num="0025">In the embodiment shown in <figref idref="f0001">FIG. 2</figref>, the first electrical contact surface 108 is located on the sidewall of a cutout area of the recess 106. The size and shape of the cutout (and thereby the size of the electrical contact surface 108) can vary to accommodate various types of contacts on the first electrical contact surface 108. In addition, by placing the first electrical contact surface 108 inside a cutout and closer to the center of the steering wheel 100, the electrical connection is more secure and protected from various types of environmental factors, such as dust or dirt or accidental liquid spills, etc. The distance between the electrical contact surface 108 and the controls on the steering wheel 100 also becomes shorter, which also makes it less prone to problems. Finally, the shape of the cutout itself serves to provide additional structural support when the steering wheel 100 is in the seated position against a protrusion having a corresponding shape in the steering axle, compared to what can be accomplished by the recess 106 by itself. The first electrical contact surface 108 can have a wide range of physical embodiments. In the embodiment shown in <figref idref="f0001">FIG. 2</figref>, the first electrical contact surface 108 is a flat metal surface, which comprises a number of electrical leads that are connected to the controls on the steering wheel 100. However, many other variations of electrical contact surfaces can be envisioned by those having ordinary skill in the art.</p>
<p id="p0026" num="0026"><figref idref="f0002">FIG. 3</figref> is a perspective view illustrating an embodiment of a steering wheel base 200 of an automotive simulator. As can be seen in <figref idref="f0002">FIG. 3</figref>, the steering wheel base 200 has<!-- EPO <DP n="10"> --> a support frame 202, which attaches to a solid surface, such as a table or similar type of surface. The support frame holds an electrical motor 204, inside which a steering axle 206 is mounted. This embodiment is typically used in various types of home environments for users who like to have their personal automotive simulator. In commercial environments, such as gaming arcades or professional training environments, there is typically no support frame 202, but instead the motor 204 is mounted into a housing of the automotive simulator using different means. Again, the specific ways of mounting the motor 204 may vary depending on the particular circumstances at hand and lie well within the capabilities of those having ordinary skill in the art.</p>
<p id="p0027" num="0027">The distal end of the steering axle 206 comprises a protrusion 208 and a second electrical contact surface 210, which together form a second adapter element that is designed to connect to the first adapter element of the steering wheel 100, described above. A magnified view of the steering axle 206, the protrusion 208 and the second electrical contact surface 210 is shown in <figref idref="f0002">FIG. 4</figref>. The various components of the second adapter element have features complementing those of the first adapter element described above, such that when the first and second adapter elements are joined together, there is a snug mechanical and electrical connection between the steering wheel 100 and the steering axle 206. In the embodiment shown in <figref idref="f0002">FIG. 4</figref>, the second electrical contact surface 210 comprises a number of spring-loaded pins, which are adapted to contact the flat metal surface of the first electrical contact surface 108. By using spring-loaded pins, it is possible to ensure an electrical connection, even in a situation where the user does not fully push the steering wheel 100 down onto the steering axle 206 during installation. However, again, it should be noted that this is merely one example of an electrical contact surface and that many alternatives can be envisioned by those having ordinary skill in the art. In the embodiment shown in <figref idref="f0002">FIGs. 3 and 4</figref>, the steering axle 206 is hollow and houses one or more cables that connect the electrical contacts on the second electrical contact surface 210 with the electronics in the automotive simulator. In the embodiment shown in <figref idref="f0001 f0002">FIGs. 1-4</figref> the surface with the electrical contacts on each adapter element is pointing upwards and downwards relative the direction of movement when interconnecting the two adapter elements. As an alternative, the electrical contacts could also be positioned on the perpendicular surfaces of each of the adapter parts since these surfaces are also facing each<!-- EPO <DP n="11"> --> other when the adapter parts are interconnected. In such a setup, the electrical connector elements could be replaced by an alternative type of electrical connectors optimized for connection on this perpendicular surface. In the embodiment described in connection with <figref idref="f0001 f0002">FIGs. 1-4</figref> and in the alternative embodiment, a common feature is that electrical connection is obtained by sliding the two adapter elements together and when in position connection surfaces are opposing each other to enable electrical connection.</p>
<p id="p0028" num="0028">It should be noted that while the above discussion refers to electrical connections, this is not intended to include power only, but also various types of data that is communicated between the steering wheel 100 and the automotive simulator. For example, in some embodiments the steering wheel 100 comprises a number of control buttons and/or a display that may show information and/or warnings to the user. Any power and information that these elements use can be transferred through the electrical connections of the steering wheel adapter. Further it should be noted that the connections could also be either solely optical connections or a combination of electrical and optical connections in such situation it would be an optical or partly contact surface on the first and the second surface on the first and the second adapter element.</p>
<p id="p0029" num="0029">Further, it should be noted that while the first adapter element 108 has been referred to as a recess and the second adapter element 210 has been referred to as a protrusion, the opposite may also be true, that is, that the distal end 104 of the steering wheel 100 has a protrusion and that the distal end of the steering axle 206 has a recess.</p>
<p id="p0030" num="0030">The adapter system shown in <figref idref="f0001 f0002">FIGs. 1-4</figref> provides a simple way to attach and detach the steering wheel 100 from the steering axle 206. As can be seen in <figref idref="f0001 f0002">FIGs. 1-4</figref> the recess 106 and protrusion 208, respectively, of the adapter system are placed such that an essentially downward vertical motion of the steering wheel 100 is used to attach the steering wheel 100 to the steering axle 206, and a corresponding upward motion is used to detach the steering wheel 100 from the steering axle 206. As a result of the placement of the recess 106 and protrusion 208, respectively, the gravity acting on the steering wheel 100 aids in bringing the first and second electrical contact surfaces 108 and 210 against each other, which aids in creating a secure electrical connection between the steering wheel 100 and the steering axle 206. However, it should be noted that there are other<!-- EPO <DP n="12"> --> embodiments in which the recess 106 and protrusion 208, respectively, can be placed such that a substantially horizontal movement (or any direction between horizontal and vertical) is used to attach/detach the steering wheel 100 from the steering axle 206. Typically, the surrounding environment of the automotive simulator will impose constraints on what particular configuration of the steering wheel adapter system is the most appropriate one, and making such a determination and the appropriate modifications of the steering wheel adapter system lies well within the skill set of those having ordinary skill in the art.</p>
<p id="p0031" num="0031">In some embodiments, the steering wheel 100 can be further secured to the steering axle 206 using a pin 500 that can be inserted into one or more holes in the first adapter and the second adapter when said holes are aligned. An example of such an embodiment is shown in <figref idref="f0003">FIGs. 5 and 6. FIG. 5</figref> shows a bottom perspective view of the steering wheel 100 being attached to the steering axle 206, prior to inserting the pin 500. In the embodiment shown in <figref idref="f0003">FIGs. 5 and 6</figref>, the pin 500 comprises one or more grooves. These grooves are configured to engage with one or more spring-loaded elements 600 that are located in the protrusion 208. <figref idref="f0003">FIG. 6</figref> shows a cross-sectional view of the pin 500 being inserted through the first and second adapter elements, respectively, to secure them together. The spring-loaded elements 600 engage with the pin 500 to prevent the pin 500 from falling out when the user turns the steering wheel 100 during operation of the automotive simulator. The pin 500 is inserted through matching holes in the first and second adapter elements, respectively, which can also be seen in <figref idref="f0001">FIG. 2</figref>. In the embodiment shown in <figref idref="f0003">FIG. 6</figref>, the grooves in the pin 500 and the spring-loaded elements 600 are symmetrically placed, so the pin 500 can be inserted from either direction, which further facilitates the installation process of the steering wheel 100 for the user.</p>
<p id="p0032" num="0032">In some embodiments, the steering wheel 100 can be secured to the steering axle 206 by a snap-lock mechanism. This snap-lock mechanism could be used if an easy, fast, and reliable mounting of a steering wheel 100 was desired. An example of such an embodiment is shown in <figref idref="f0004">FIGs. 7</figref>, <figref idref="f0005">8</figref>, <figref idref="f0006">9</figref>, and <figref idref="f0007">10</figref>. The steering wheel base 200 is shown in <figref idref="f0004">FIG. 7</figref> and comprises the steering axle 206. The steering axle 206 further comprises a protrusion 208, a second electrical contact surface 210, and a barb 701. The steering wheel 100 is shown in <figref idref="f0005">FIG. 8</figref> and comprises a steering handle 102 for holding onto the steering wheel 100, a first electrical contact surface 108, together with a beam 801 that can act as a<!-- EPO <DP n="13"> --> spring placed on a distal end 104 of the steering wheel 100. The beam 801 comprises a second protrusion 803 that includes a first surface 804 and a second surface 805. A magnified view of the distal end 104 of the steering wheel 100 can be seen in <figref idref="f0006">FIG. 9</figref>. The beam 801 can be bent in the direction towards the proximal end of the steering wheel 100 by pushing on the part of the beam 801 that is furthest away from the center of the steering wheel 100, such that the protrusion 803 connected to the beam is lowered into a recess surface 106 of the distal end 104 of the steering wheel 100. Specifically, when the beam 801 is bent in the direction away from the first surface 804, the first surface 804 of the protrusion 803 is lowered into the recess surface 106. When the beam 801 is bent in the direction towards the first surface 804, the first surface 804 of the protrusion 803 pops up above the recess surface 106.</p>
<p id="p0033" num="0033">In one embodiment, the snap-lock mechanism comprises beam 801 placed on the distal end of the steering wheel 100 and the barb 701 placed on the distal end of the steering wheel base 200. When the steering wheel 100 slides onto the steering axle 206, the beam 801 bends as the first surface 804 is pushed by the barb 701. When the steering wheel 100 slides all the way until the steering wheel is aligned with the steering axle 206, the beam 801 returns to a neutral position and the first surface 804 no longer contacts the barb 701 and the first surface 804 pops up. The barb 701 is stopped by the second surface 805 and locks the steering wheel 100 to the steering axle 206. If the steering wheel 100 was pushed in the opposite direction the way that it was slid on to the steering axle 206, the second surface 805 would hit the barb 701 and block the sliding movement of the steering wheel. Thus, it is in a locked position such that the steering wheel 100 is aligned with the steering axle 206 as shown in <figref idref="f0007">FIG. 10</figref>. To remove the steering wheel 100, the beam 801 is pulled towards the proximal end of the steering wheel 100 until the second surface 805 is free of contacting the barb 701. Now the steering wheel 100 can slide off the steering axle 206. This lock mechanism could also be carried out in an embodiment where the barb 701 is placed on the distal end 104 of the steering wheel 100 and the beam 801 is placed on the distal end of the steering axle 206 in the same manner as the position of the protrusion 208 and recess 106 can be swapped.</p>
